AXICrossbar: absorb data width setting when building crossbar
...
This patch allows the AXICrossbar to absorb non-default datawidths
when the crossbar is built.
e.g. in the case of a 64-bit AXICrossbar, without this patch the
crossbar was only connecting the bottom 32 bits.

The use of os.system together with cd is a problem because it changes the

When finding the longest 1 window when write leveling, if the last tap

judge it as 0.
Add one more iteration and force 0 in that one to handle the last 1.

software/liblitedram: scale up values when finding CMD delay
...
The delay finding code is based on integers, and when divided by the
count, rounding error will be quite easy to happen.
Scale up all delay value by 256x to reduce rounding error.

On some boards, the working delay range found may be not so consecutive.
Considering this to be some inference, we should only count the biggest

cpu/openc906: fix the semantics of self.reset
...
LiteX defaults to active-high reset signals, but OpenC906 uses
active-low ones, and the self.reset signal of openc906 module is wrongly
wired that it will force the CPU to run instead of force it to reset
(because it is ORed and then feed to the active-low reset line).
Fix this by using AND and inverting self.reset.
